技能偏向型技术进步存在吗?——来自中国的经验证据

Is There Skill Biased Technological Change? Evidence from China

本文利用1978—2007年时间序列数据考察我国技能偏向型技术进步的存在性,以及不同类型技术进步技能偏向性的差异。分析显示,我国技术进步引致技能型劳动需求增长,进而导致劳动力市场收入结构变化而出现技能溢价。本文还将技术进步细分为中性、非中性和资本体现式等不同类型,发现不同类型技术进步都呈现技能偏向特征,其中资本体现式技术进步与技能需求和技能溢价的互补关系更强,说明蕴含前沿技术的设备投资高增长引发技能偏向型技术进步,现阶段我国技术进步呈现物化和技能偏向双重特性。

The paper makes an empirical study on the presence of the skill biased technological change and the function difference of the different kinds of technological change with China＇s data from 1978--2007. It points out that China＇s technology can conduct skill demand growth, and make the structure of labor market variable and the skill premium, namely there is skill biased technological change in China. To subdivide technology to neutral, non-neutral, and capital specific technology, it shows that all kinds of technology are to be skill-biased, and the capital specific function is the most, all these mean that the technological change contained in the equipment grows fast to make the skill biased technological change develop, and the technological change takes the characters of both the capital specific and skill biased.
